“Hot Tub Rash” (Pseudomonas Dermatitis / Folliculitis)

If contaminated water comes in contact with a person’s skin for a long period of time, it can cause a rash called hot tub rash, or dermatitis. Hot tub rash is often caused by infection with the germ Pseudomonas aeruginosa. This germ is common in the environment (for example, in the water and soil) and is microscopic, so it can’t be seen with the naked eye.

Symptoms of hot tub rash include:

  • Itchy spots on the skin that become a bumpy red rash.
  • The rash is worse in areas that were previously covered by a swimsuit.
  • Pus-filled blisters around hair follicles.

Hot tub rash can affect people of all ages. Most rashes clear up in a few days without medical treatment. However, if your rash lasts longer than a few days, consult your health care provider.
